Reference variable from object in another class

Question

I've got two classes, one called "Territory" which constructs an object with the following variables: "posX" and "posY", like this:

public Territory(int column, int row)
{
    posX = column;
    posY = row;
}

Then in another class, "World" I do the following:

Territory territory1 = new Territory(0, 0);

But then when I try to reference some of the variables from that object, i.e. like this:

System.out.println("Coordinates: " + territory1.posX);

I get the error:

cannot find symbol - variable territory1

Any help?

EDIT:

Here are the full classes:

Territory:

public class Territory
{
    public int posX;
    public int posY;
    public int armies;
    public String owner;

    public Territory(int column, int row)
    {
        posX = column;
        posY = row;
        armies = 0;
        owner = null;
    }
}

World:

public class World
{
    public World()
    {
       Player player1 = new Player();
       Player player2 = new Player();

       Territory territory1 = new Territory(0, 0);
       Territory territory2 = new Territory(1, 0);
       Territory territory3 = new Territory(0, 1);
       Territory territory4 = new Territory(1, 1);     
    }

    public java.lang.String toString()
    {
        System.out.println(territory1.getposX);
    }
}

Issue is probably with the scope of territory1 though, based on the error, and not with the access modifiers of its fields. — Voicu

your toString() method doesn't recognize 'territory1' because it was declared in the other method

This should work

public class World
{
     Territory territory1, territory2, territory3, territory4;

    public World()
    {
       Player player1 = new Player();
       Player player2 = new Player();

       territory1 = new Territory(0, 0);
       territory2 = new Territory(1, 0);
       territory3 = new Territory(0, 1);
       territory4 = new Territory(1, 1);     
    }

    public toString()
    {
        if( territory1 != null)
            System.out.println(territory1.posX);
    }
}

I tried both of these and neither worked, still getting the same error. I updated the post to show full code.

@RyanEder nahh. of course that won't fix your problem. why don't you post your full code earlier. your toString() method doesn't recognize territory1 because it was declared in the other method

@Voicu not aware of it. It seem that my answer is totally out! deleting

If you are not able to access the attribute of a class in another class then it means the attribute is not visible to that class. Check the access specifier for the attributes. You may have to use a getter(public method to get the value of a private variable) for the variable.
